Gravity and Kip Thorne's ideas concerning wormholes?

Let's ignore the wormhole is able to yank things into itself for the time being. A WH placed on the ceiling would only be influenced by Earth's gravity on the plane of the mouth, just as the greatest entropy of a black hole is on the plane of the event horizon. If a body were half in and half out, it would experience a tug based on Newton's force law. It would not immediately fall into the living room, however, unless the acceleration due to gravity overcomes the ability to remain in a free fall state. For example, sticking your arm through would do very little. But placing more of your body in, would cause you to feel pulled based on the proportion within the gravity field. Similarly, it gets easier to climb in the more your body is on the other side. Naturally, there is no scientific basis for any of this. A WH would devour whatever is within its curvature of space.
